- the letters A, B, and C will be used as a suffix after the reference numerals to distinguish between the different embodiments depicted in FIGS. 6-8 , it being understood that the description of the features provided above with the same reference numeral without the suffix is applicable.
- the specific structural features of the cylindrical body 100 described above are applicable to each of the cylindrical bodies 100 A, 100 B, 100 C described in FIGS. 6-8 .
- the cylindrical bodies 100 A, 100 B, 100 C are only used herein to describe the different types of materials that can be used to form the cylindrical body 100 .
- the cylindrical body 100 A is formed of a single material. Specifically, in this embodiment the cylindrical body 100 A is formed entirely of a metal material, such as carbon steel or the like. Thus, the bore 120 A and the annular groove 110 A are formed directly into the solid metal material of the cylindrical body 100 A.
- FIG. 7 a second embodiment of the cylindrical body 100 B is illustrated.
- the cylindrical body 100 B is formed primarily of a metal material in much the same manner as the cylindrical body 100 A.

- the rubber overmold 129 B may be molded over the floor 111 B of the annular groove 110 B to at least partially cover the floor 111 B of the annular groove 110 B. Coating or otherwise covering the floor 11 B of the annular groove 110 B prevents metal-on-metal contact when the elongated bar 200 is positioned within the annular groove 110 B during a workout routine as discussed in more detail below with reference to FIG. 3 .
- the elongated bar 200 will contact the rubber overmold 129 B, which provides a resilient contact region between the elongated bar 200 and the cylindrical body 100 B and avoids the loud noise that might otherwise result from the metal-on-metal contact between the elongated bar 200 and the cylindrical body 100 B.
- the cylindrical body 100 C comprises a tube portion 130 C and an overmold portion 140 C.
- the tube portion 130 C is formed of a first material having a first hardness value and the overmold portion 140 C is formed of a second material having a second hardness value, the first hardness value being greater than the second hardness value.
- the tube portion 130 C may be formed from a steel tube, such as one that is seamless by being formed using a drawn over mandrel (DOM) technique.
- DOM drawn over mandrel
- the tube portion 130 C of the cylindrical body 100 C is a round mechanical tube formed of carbon steel.
- the tube portion 130 C has a length and an inner surface 131 C, and it is the inner surface 131 C of the tube portion 130 C that defines the bore 120 C.
- the tube portion 130 C may have a thickness T of approximately 0.065 inches, although other thicknesses can be used as desired.
- the inner surface 131 C of the tube portion 130 C may be coated with hard chrome having a thickness of between 0.0005 and 0.001 inches that is smooth and free of surface imperfections. As noted above, the thickness of the hard chrome may affect the dimensions of the first diameter D 1 of the bore 120 C.
- the overmold portion 140 C of the cylindrical body 100 C is formed of a rubber material, such as one having a Shore A durometer value of between approximately 70 and 80, and more specifically approximately 75 (similar to that which is used for outdoor roller skate or skateboard wheels).
- the rubber material of the overmold portion 140 C of the cylindrical body 100 C may be styrene-butadiene rubber (SBR).
- the overmold portion 140 C is formed of a rubber and is therefore somewhat resilient, due to the durometer value noted above the overmold portion 140 C will still be somewhat rigid so that if the cylindrical body 100 C is positioned on a horizontal surface such as a floor and is made to support a substantial amount of a user's weight, the cylindrical body 100 C will not just collapse or significantly indent itself.
- the rubber material is somewhat of a hard rubber so that the cylindrical body 100 C will still be able to substantially maintain its shape during use.
- the overmold portion 140 C is molded to the tube portion 130 C of the cylindrical body 100 C along the entirety of the length of the tube portion 130 C.
- no portion of the tube portion 130 C protrudes beyond the overmold portion 140 C at the first and second ends 101 C, 102 C of the cylindrical body 100 C.
- the tube portion 130 C is exactly flush with the overmold portion 140 C at the first and second ends 101 C, 102 C of the cylindrical body 100 C such that it is a combination of the ends of the tube portion 130 C and the ends of the overmold portion 140 C that forms the first and second ends 101 C, 102 C of the cylindrical body.
- no portion of the overmold portion 140 C extends into the bore 120 C or into the chamfer 123 C.
- the bore 120 C is formed through the tube portion 130 C as discussed above.
- the annular groove 110 C is formed into the overmold portion 140 C.
- the entirety of the outer surface 104 C of the cylindrical body 100 C is formed of a rubber material. This can be beneficial for use of the device on a hardwood floor. Specifically, during use the cylindrical body 100 C is in rolling contact with a floor, which can be a carpet, a hardwood floor, tiles, vinyl or the like.
- the outer surface 104 C of the cylindrical body 100 C When in rolling contact with a floor, the outer surface 104 C of the cylindrical body 100 C is in direct surface contact with the floor. Thus, forming the outer surface 104 C of the cylindrical body 100 C out of a rubber material will reduce the likelihood of causing damage to the floor surface upon which the cylindrical body 100 C is positioned during use.

- the elongated bar 200 is positioned within the annular groove 110 , minimal (if any) movement of the elongated bar 200 in the direction of the longitudinal axis A-A of the cylindrical body 100 is permitted.
- the elongated bar 200 nests within the annular groove 110 and remains so positioned due to the combination of the depth d 1 of the annular groove 110 , the diameter D 2 of the elongated bar 200 , and the length L 3 of the annular groove 110 .
- the annular bar 200 When the elongated bar 200 is nested within the annular groove 110 , the annular bar 200 is able to readily slide or roll within the annular groove 110 (or relative to the annular groove 110 ) in a direction transverse to the longitudinal axis A-A of the cylindrical body 100 and along the direction of the longitudinal axis C-C of the elongated bar 200 .
- a user With the elongated bar 200 in the annular groove 110 , a user will grip opposite ends of the elongated bar 200 while the user is in a push-up (or modified push-up) position, putting all (or some) of his or her weight on the elongated bar 200 .
- the user will be able to move the elongated bar 200 from left to right and from right to left (in both opposing directions of the longitudinal axis of the elongated bar 200 ), which will cause the cylindrical body 100 to roll along the floor or other horizontal surface upon which it is resting in the same direction of movement of the elongated bar 200 .
- the cylindrical body 100 will roll along the floor and the elongated bar 200 will remain nested within the annular groove 110 during this exercise routine.
- the portion of the elongated bar 200 (the longitudinal location of the elongated bar 200 ) that is positioned within the annular groove 110 will change.
- the elongated bar 200 is also able to pivot about an axis that is perpendicular to the longitudinal axis C-C and that intersects the portion of the elongated bar 200 that is in surface contact with the floor 111 of the annular groove 110 to work different muscles of the user's body.
- the elongated bar 200 can be pivoted so that one end of the elongated bar 200 is tilted upwards while the other end of the elongated bar is tilted downwards.
- the system is illustrated with the elongated bar 200 positioned within the annular groove 110 of the cylindrical body 100 and with two of the resistance bands 300 detachably coupled to the elongated bar 200 .

- the user can work out his or her biceps by curling the elongated bar, triceps by doing overhead extensions, deltoids by doing shoulder presses, trapezius by doing shrugs, quadriceps by doing squats, or the like.
- the user may rest one of his or her feet on the cylindrical body 100 when doing these exercises to ensure that the cylindrical body 100 remains in surface contact with the floor with the resistance bands 300 trapped between the cylindrical body 100 and the floor.
- the user may use the resistance bands and the elongated bar 200 separate from the cylindrical body 100 by the user standing on the central portion of the resistance bands 300 and doing the above-noted exercises.
- the system is illustrated with the elongated bar 200 positioned within and through the bore 120 of the cylindrical body 100 . Because the first diameter D 1 of the bore 120 is larger than the second diameter D 2 of the elongated bar 200 , the elongated bar 200 is able to be inserted into and through the bore 120 . In this figure, only one of the members of the two-piece bar is illustrated positioned within the bore 120 . However, the members can be coupled together and then inserted into the bore 120 , or a single-piece elongated bar can be used.

- the user can then slide/roll the elongated bar 200 and the cylindrical body 100 in a direction away from and towards the user to achieve an abdominal/core/full body workout. Variations of this particular workout can be achieved as would be understood by persons of skill in the art, such as by the user being positioned on his or her toes and then sliding/rolling the elongated bar 200 and the cylindrical body 100 in a direction away from and towards the user.
- the resistance bands 300 can be coupled to the elongated bar 200 when the elongated bar 200 is positioned within the bore 120 of the cylindrical body 100 and exercise routines can be conducted with the system 1000 in that position.
- the first member 210 of the two-piece elongated bar 200 may be desirable to use for this exercise because the first member 210 has the two textured regions 215 , is longer than the bore 120 , and is not as long as the elongated bar 200 in its entirety so it takes up less space during a workout routine. Furthermore, the first member 210 has the female threaded connector 212 , so there are no protruding structures that can damage the user's hand or cause discomfort during use.
- the cradle 400 may be used for storage of the cylindrical body 100 , or it may be used as a sort of training wheels that prevents the cylindrical body 100 from rotating along the floor during use. Thus, the above exercises can be conducted while the cylindrical body 100 is nested in the cradle 400 to prevent rolling movement of the cylindrical body 100 during the workout routine.
- the cradle 400 may be sold together with the cylindrical base 100 , the elongated bar 200 , and the one or more resistance bands 300 in the kit. In other embodiments, the cradle 400 may be sold separately from the other components on an as-needed basis.
